As part of its efforts to supplement funds for activities including the Prize Essay and publication of Terrae Incognitae, the Society markets a small selection of items designed to match the themes of discovery and exploration. These include an attractive tie and sets of postcards. The concept for the Terrae Incognitae design is based on the 1663 Pieter Goos Map (courtesy Glen McLaughlin Collection), and designed and produced by Marianne Hinckle, Año Nuevo Island Press/Nuevo Mundo designs.
